CLOTHES-WIRING.

Specification of Letters Patent.

Patented May 30, 1916.

Application filed September 24, 1915. Serial No. 52,336.

To all whom it may concern.

Be it known that I, TILLIBALD TRINKs, a citizen of the United States, and residing in the city of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented or discovered new and useful I mprovements in Clothes-Wringers, of WlllCll' the followin is a specification.

My invention consists in a new and improved laundry or clothes wringer, and more particularly relates to the method of mounting the wringer rolls and in means for releasing the resiliently mounted roll in case of emergency, as when the hand or clothing of the operator becomes caught 1n the wringer or a garment passing through the rolls becomes Wound around one of the latter.

In the majority of wringers springs of some character are employed to resiliently press the rolls together, and such wringers are sometimes provided with emergency releasing means which are universally mounted on top of the wringer, thus unduly increasing the height of the mechanism and placing the release device at a great distance from the normal position of the operators hands while workin This latter feature delays the release 0 the rolls and thus aggravates accidents.

My improved wringer is of low and compact structure which may be conveniently mounted on top of a washing machine or other support but will still be within easy operating position. The roll mounting is compact and efficient, permitting the two ends of the roll to be moved independently, thus allowing the wringer to accommodate itself to garments of varying thickness across their width as they pass through the wringer. Means are provided for adjusting the roll pressure accurately. The releasing means are placed convenient to the hand of the operator so that in case of accident, the release may be accomplished without abnormal effort or shifting of the hands.

Many novel features of construction and arrangement of parts will appear from the following description.

In the accom anying drawings, which are merely intende to illustrate the principles of my invention and not to limit the scope of the same to the embodiment shown, Figlower roll. nected together as by gearsefand f. The

' ure 1 is a front elevation of my improved wringer, a portion of the releasing device being broken away in section for the sake of clearness; Fig. 2 is a vertical section of the same taken along the line II-II in. Fig. 1; Fig. 3is a horizontal section taken along the line IIIIII in Fig. 2; Fi 4 is a horiaontal section taken along the line IVIV in Fig. 2; Fig. 5 is a vertical section taken along the line VV in Fig. 7, showing my improved release applied to another form of wringer; Fig. 6 is a horizontal section of the same taken along the line VI-VI in Fig. 5, and Fig. 7 is. a broken front elevation of the same, showing the left end of the wringer.

The following is a detailed description of the drawings, reference being first had to Figs. 1, 2, 3 and 4. The frame of the wringer is preferably cast integrally of metal and is comprised of the following main elements. A is a horizontal bed plate having its top surface preferably inclined from the center toward front and rear to shed water. B represents a depending transverse flange at either end of said bed plate, preferably perforated as at 1 to receive bolts or other members for the attachment of the wringer to a support, such as a washing machine.

C is a longitudinal vertical web or rib inte%al with the bed plate and the end flanges.

represents end plates extending up at either end of the bed plate and inset from the flanges B. From each of said end plates D extend a pair of standards 2 spaced apart by the seat 3 open at its upper end. As the two ends of the wringer are substantially identical in structure, I will describe one of them as characteristic. In the bottom of the seat 3 is mounted a journal box 4 in which the axle 5 of the lower wringer roll E is journaled. One end of said axle protrudes beyond its journal box, as shown in Fig. 1, for the mounting of a gear wheel or some other means for applying rotary motion to the lower roll. F is the upper roll whose axle 6 is journaled in a box 7 slidably mounted in the seat 3 above the lower box 4, the upper roll pressing down on the The rolls are operatively conboxes are held against otherfthan vertical movement in said seats by means of vertical ribs8 on the boxes engaging vertical grooves 9 on the inner faces of the standards. The outer vertical faces of said standards 2 are provided with vertical slideways 10 in which slide the vertical lips 12 on the inner faces of the depending legs 13 of the substantially inverted U-shape pressure saddle G whose horizontal bridge is provided with a depending pressure block 14 which bears on the top of the upper journal box 7 15 represents vertical bolts Whose lower squared ends are stepped through squared holes 16 in the bed plate A and whose downward movement is limited by the collars 17. The lower extremities of the bolts 15 are pierced to receive cotter pins 18 to limit the upward movement of said bolts, said bolts being capable of considerable vertical movement between the limits thus fixed. The squared shanks of the bolts prevent their rotating.

The lower end of each leg 13 is provided with an outwardly extending horizontal flange 19 provided with a spring seat 20 on its upper face and a vertical hole 21, concentric with said seat, for the passage of the bolt 15. Upon each bolt 15 is coiled a helical spring 22 whose lower end engages the seat 20 while its upper end bears against a cross head 23 through which both bolts 15 pass. 24 represents thumb nuts screwed on the upper ends of said bolts against said cross head. It is evident that by adjusting the thumb nuts the resilient pressure exerted upon the upper roll may be nicely reg ulated.

H is a graduated age bar extending upwardly from the sa dle Gin proximity to an indicator on the cross head 23 so that the exact pressure desired may be imparted to the rolls.

It is evident that since the ends of the upper roll are resiliently enga d by separate spring mechanisms, the roll is free to tilt in relation to the lower roll to permit the passage of garments of varying thickness throughout their width without releasing any portion'of the garment from efiicient wringing action.

I will now proceed to describe my roll releasing mechanism. 7

The squared butts of the bolts 15 are rovided with notches 25 on their front aces which are normally engaged by the edges of ture 26 in the vertical web C. Thus the bolts are held in their depressed position shown in the drawings. The lock plate I is provided with a squared aperture at its center in which is seated the squared vertical ivoted on arm of a bell lever 27 which is the knife edge 28 formed on the ower edge of the aperture 26. The horizontal arm of the lever 27 extends forwardly and is con-,

nected by the bar 29 with the corresponding bell lever at the other side of the machine.

It is evident that a sharp downward blow on the releasing bar 29 will throw the locking plates I at each end of the machine forwardly, thus releasing them from the notches in the bolts 15, and permitting the helical springs to throw said bolts upwardly and thereby release the spring pressure upon the upper roll. The release bar is convenient to the hands of the operator, so that the release may be accomplished without abnormal movement of the hand. The ratio of the levers is such that the mere weight of the clothes, as they pass through the wringer, resting upon the bar, will not operate the release, but a sharp blow of the hand upon said bar is required. The bolts may be reset, after release, by loosening the thumb nuts, depressing the bolts and moving the locking plates back into their engaging position. The thumb nuts may then be tightened to produce the proper spring pressure which adjustment is facilitated by-the use of the gage bar H.

I will now proceed to describe my release as applied to another form of wringer shown in the remaining figures of the drawings. In this case the upper roll F is journaled above the lower roll in boxes which are mounted on the free ends of brackets 30 which are pivotally supported at their rear ends on the frame of the machine. Bolts 31 extend down through said brackets 30 and have their squared ends stepped in squared holes in thebed plate of the machine, their upward movement being limited by the cotter pins 32 and their downward movement by the collars 33. Helical springs 34 are 30 and thumb nuts 35 screwed on the upper ends of said bolts. By tightening the thumb nuts the pressure of the upper roll upon the lower roll is regulated. The squared butts of the bolts 31 are provided wlth notches 36 which are engaged by the inner or short ends of the bell levers 37 which are pivoted at their angles to the frame of the machine and have their forwardly extending long armsconnected together by the release bar 38.

It is 'evident that a downward blow of the release bar 38 will disengage the levers from the notches and permit the bolts to spring upwardly, releasing the spring pressure on the'upper roll.

It IS evident from the foregoing that my wringer is of simple, compact, inexpensive, yet durable construction. Its parts are few and are subjected to a minimum of wear. Such parts as may become worn or impaired may be readil replaced at small expense and without t e use of special tools. The release is properly. placed for convenient and instantaneous operation so that accidents may be avoided or rendered less serious.
